Comment alert going to wrong address

I have a blog at the domain jbosman.net.
I have my wordpress installation set to email me whenever a comment is posted on my blog.
I just discovered that these emails are going to the address @jbosman.com, and not .net

I can’t figure out why this is. I’ve even gone into the wordpress database, but every instance of my email address points to the .net address. Why would it be sending emails to jbosman.com?

Is there someplace I haven’t checked that might be responsible?
